AUXILIARY STEAM-PIPE FOR RADIATORS.

SPECIFICATION forming part of Letters Patent No. 505,136, datedSeptember 19, 1893. A nmnn filed June 6, 1393. M1 No. 476,750. onmodel.)

To all whom it may concern.-

Be it known that 1, JOHN B. SMITH, a citizen of the United States, and aresident of Chicago, county of Cook, and State of Illinois, haveinvented new and useful Improvements in Auxiliary Steam-Pipes forRadiators, of which the following is a specification, reference beinghad to the annexed drawings, illustrating the invention, in which Figure1,is a perspective representation of a steam radiator with my auxiliarypipe at tached and in position for use; Fig. 2, a plan view of the same.

This invention consists in means for conducting the main bodyof steam tothe ordinary radiator near its bottom portion as is now the custom, andin addition thereto to conducting a continuous small quantity of steaminto the upper opposite portion of the radiator. To accomplish thispurpose a small steam pipe is attached to, and communicates with themain steam induction pipe wholly outside of the radiator and extends tothe upper portion of the loop-pipe farthest from the main inductionpipe. The purpose of ejecting steam into the said loop-pipe is toproduce an equilibrium throughout the several loops of the radiator andprevent the water of condensation from rushing back and forth thereinand producing a disturbing noise by vibrating the radiator. It oftenoccurs that cold air, after the steam is shut olf, accumulates in theloops and prevents, for some little time the steam, when let on again,from operating properly to heat the radiator as the latter is at presentconstructed. But by the use of said auxiliary pipe such cold air isimmediately driven down and out at the steam exit pipe, and anequilibrium is instantly produced.

A, represents an ordinary steam radiator, and B is the steam inductionpipe.

, C, D, represent the said auxiliary pipe and its couplings. This pipe,by a suitable screw thread, is connected with and communicates with theinduction pipe, or steam supply pipe B, and extends upward nearly to thebends of the loops forming the radiator, and then across said loops tothe outer upper portion of the opposite loop from the loop the steamsupply enters, and there enters by a suitable screw thread the upperportion E of said loop whereby steam in the pipe B will supply, from aone-fourth inch pipe, steam to the loop F at E during all the time thepipe B supplies the radiator with steam in the usual manner. It isimmaterial, however, in what direction the pipe 0 runs to reach thepoint IE; it may run under the loops, between them, or back of them, asshown at Fig. 1, as most convenient. A cock G is inserted in thecoupling Hto determine if the passage in the pipe Cis unobstructed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent of the United States- With a steam radiator having alower steam supply-pipe, the combination of a small eX- terior steampipe at its lower end attached to and communicating with the exteriorport-ion of said supply pipe, and its upper end attached to andcommunicating with the upper portion of the opposite loop from where thesaid supply enters; substantially as and for the purpose specified.

JOHN B. SMITH.
